Scientists know that some types of congenital heart defects can be related to an abnormality of an infant's chromosomes, single gene defects or environmental factors.n most cases when a baby is born with a congenital heart defect, there is no known reason for the heart to have formed incorrectly.

Best Answer: From Oahu, you can just barely see Molokai from the east side of the island when weather conditions are right. You cannot see Kauai from the west side of Oahu.
Along with the rest of the Hawaiian Islands, Oahu is one of the largest and northernmost islands of Polynesia. In the greatest dimension, this volcanic island is 44 miles (71 km) long and 30 miles (48 km) across. The length of the shoreline is 227 miles (365 km). The island is the result of two separate shield volcanoes: WaiÊ»anae and KoÊ»olau, with a broad valley or saddle (the central OÊ»ahu Plain) between them. The highest point is KaÊ»ala in the WaiÊ»anae Range, rising to 4,003 feet (1,220 m) above sea level.
